Week Ten: Embryo is now a Fetus

From this week until birth, the developing organism is called a fetus.

The fetus is now the size of a small strawberry.

The feet are 2mm long (one tenth of an inch).

The neck is beginning to take shape.

The body muscles are almost developed. Baby has begun movement.

While still too small for you to feel, your little one is wriggling and shifting.

The jaws are in place. The mouth cavity and the nose are joined.

The ears and nose can now be seen clearly.

Fingerprints are already evident in the skin.

Nipples and hair follicles begin to form.

The unborn baby is now called a fetus. Though the fetus is constantly moving, you will not be able to actually feel fetal movement for several more weeks. All of the organs, muscles, and nerves are in place and beginning to function. As the hands and feet develop fingers and toes, they have lost their paddle like look. The touch pads on the fingers form and already have fingerprints.

During this week of pregnancy the crown to rump length of the fetus is 0.9 inch to 1.2 inches (22 to 30mm), weight 0.07 ounce (2gm). They are now on the way to forming their testicles or ovaries, getting ready for the next generation. Until the ninth week of fetus development, the fetal reproductive apparatus is the same one for the both sexes. The head is still large and curves into chest.

Each week your uterus grows larger with the baby growing inside it. You may begin to see your waistline growing thicker by this time. A pelvic exam will detect that your uterus has grown from it's normal, size of your fist, to a little bigger than a grapefruit.
